      @stephenw10 said in LACP not working:

      The complete output from show lag on the switch contains the Partner info and PDU stats at the end which show what is connected and on which port. It also shows the system wide lag parameters at the top on my switch. It would be good to compare those.
      Your switches are different to mine though, the output is very similar but not identical.

      You posted a more complete output here: https://forum.netgate.com/post/947906

        Ok so from that we can see that the system ID the switch sees on both those ports matches the ID pfSense has set on it's lagg ports.

        However we cannot see the switch system ID. pfSense sees it as: 0001,60-9C-9F-4B-80-8C

        That info is at the top of the show lag output from the switch as I showed above:

        SSH@ICX6450-24P Switch>show lag
        Total number of LAGs:          1
        Total number of deployed LAGs: 1
        Total number of trunks created:1 (123 available)
        LACP System Priority / ID:     1 / 609c.9f54.14f2
        LACP Long timeout:             90, default: 90
        LACP Short timeout:            3, default: 3
        

        It obviously should match but....

        What we can see is that the switch has recorded precisely 0 lacpdus received.

          what are you suggesting ?
          if i connect a different switch the ports comes online and shows the LACP is fine.

            To that switch or to pfSense?

            I have once seen a similar issue to this that was eventually resolved by simply rebooting the switch stack. Something no-one had thought to do because generally switches do not require that sort of thing.

            Beyond that I would try a lagg to ports on the same switch to remove the cross-chassis LACP as an issue.

            Then I'm out of suggestions. You probably need to get Brocade/Rukus/Commscope support involved at that point.

              Hi Steve
              I can do the reboot tonight. When I am logged in shut reboot its will reboot both switches ?

                I can't answer that I only have a single Brocade switch. I would hope there is some failover happens. I've never configured that.
                Be sure to have saved the running config. Have a recovery plan etc....

                    The only thing I have not seen from your switch is the LACP ID value. My switch shows that at the top of the show lag output but either yours doesn't or you're just not including it here.

                    We can guess it's 609c.9f4b.808c because that's what the error logs show and the ifconfig from pfSense. But if it isn't that it would be mismatched.

                      Thank you for your answer Steve,
                      i have managed to get the 609c.9f4b.808c corrected. it was the second Mac of a different LAG.
                      i've remvoed that lag and the issue is fixed.
                      both Pfsense and Switch share the same LACP ID now.
                      what information do you need from the switch?

                        Ah, so the lag to pfSense came up correctly with the 2nd lag removed?

                        On my switch the first lines of output from show lag are:

                        SSH@ICX6450-24P Switch>show lag
                        Total number of LAGs:          1
                        Total number of deployed LAGs: 1
                        Total number of trunks created:1 (123 available)
                        LACP System Priority / ID:     1 / 609c.9f54.14f2
                        LACP Long timeout:             90, default: 90
                        LACP Short timeout:            3, default: 3
                        

                        I was hoping to compare that output with what you switch(es) show. But they are not the same as mine it may not show that.

                        This seems like it could be something like different lacp IDs between the two switches in the stack. I have no way to test that.

                          Ah, so the lag to pfSense came up correctly with the 2nd lag removed?

                          On my switch the first lines of output from show lag are:

                          SSH@ICX6450-24P Switch>show lag

                            Ok, so it's still down there. Removing the other lag did not allow it to come up?

                            We see the LACP ID though and as expected it matches what pfSense is seeing.

                              What lag are you referring to ? Do you mean recreate the lag ?

                                i have managed to get the 609c.9f4b.808c corrected. it was the second Mac of a different LAG.
                                i've remvoed that lag and the issue is fixed.

                                Whatever you removed there that fixed it.

                                  i am not sure i can follow sorry :)
                                  i havent removed anything and its not fixed yet.
                                  my question was do you meant i have to remove the already created LAG and create it again?

                                    You may well have to re-deploy it on the switches to have it use the new settings.

                                    I can only make an educated guess at this point. 😉

                                    What exactly did you do before then when you said that was fixed? And what was it that was fixed?

                                      I have deleted and created the LAG over.
                                      but long time but it still blocking it.

                                      in the firewall or switch I don't see any logs about the LACP.
                                      what are we missing?😞
